Bulbophyllum crabro

Bulbophyllum crabro is the orchid long grown as Monomeria barbata: a creeping plant with widely spaced, single-leaved pseudobulbs and arching sprays of 10–15 odd, bearded, wasp-like flowers in winter and early spring. It grows mostly on rocks, and sometimes on trees, in forests from Nepal and Assam through Myanmar, south-west China and northern Indochina to Malaya and Sumatra. It needs a monsoon rhythm: warm and wet in summer, cooler and drier in winter.
